• Your role is to build an AIOps platform from scratch that connects infrastructure operational data with AI to predict failures and enable automated responses.
• Beyond simple monitoring, the team's goal is to realize Closed-loop automation of Detection $\rightarrow$ Diagnosis $\rightarrow$ Response $\rightarrow$ Verification.

Responsibilities

• Design, build, and operate an infrastructure-specialized AIOps platform, and select/customize open-source anomaly detection engines to eliminate alert noise based on dynamic thresholds.
• Build heterogeneous infrastructure data collection pipelines for metrics, logs, traces, etc., and implement interfaces for integration with internal LLM and incident knowledge bases.
• Preemptively detect capacity exhaustion and performance degradation trends through time-series forecasting, and implement failure propagation path visualization and correlation analysis functions to support RCA.
• Collaborate with Infra Automation SE to continuously expand the scope of Closed-loop automation (Detection $\rightarrow$ Diagnosis $\rightarrow$ Response $\rightarrow$ Verification) and Self-Healing policy application.
• Measure MTTD/MTTR improvement trends and establish an AIOps maturity roadmap to report performance.

• Experience in building End-to-End data pipelines, proficiency in at least one primary development language, and experience in large-scale metric/log processing and utilizing time-series DBs and search engines.
• Linux system administration capabilities and an understanding of fundamental infrastructure concepts such as infrastructure monitoring, network, storage, and virtualization.
• Deep understanding of open-source tools with experience in customizing and internalizing them, and the ability to independently read and apply English technical documentation.

Nice-to-haves

• Experience in building/operating AIOps or monitoring platforms and an understanding of time-series anomaly detection algorithms.
• Experience in building LLM API integration pipelines and prompt engineering.
